What is the throttle body and how does it work?

The throttle body is an air metering device mounted between the air filter and snorkel, and the intake plenum. Within the throttle body is a movable throttle plate whose position controls the amount of air that enters the engine to determine engine speed. Throttle body designs vary. Some incorporate an idle air control valve, throttle position sensor, and other electronic throttle controls. The throttle plate in the throttle body can be controlled directly by an accelerator pedal cable or fully electronically in the newest drive-by-wire systems.

When to consider replacing the throttle body:

  • Check engine light and/or reduced power warning light is on. Most modern throttle bodies have electrical components, such as a throttle position sensor. These components are monitored by the powertrain control module (PCM). If the check engine light or reduced power warning light comes on, a mechanic will determine if any of the stored trouble codes implicate a throttle body malfunction.
  • Wrong idle speed. Carbon deposits in the throttle body, particularly around the movable throttle plate or in the idle air control valve, can cause the engine idle speed to be too low or too high.
  • Poor transmission shifting. In some applications, transmission shift timing relies on signal outputs from the throttle body. If the throttle position sensor is defective, that might adversely affect shift timing and feel.

How do mechanics replace the throttle body?

  • The engine cover is removed, if necessary.
  • The flexible rubber snorkel from the air filter housing to the throttle body is disconnected. Typically, the connection is made with a large stainless steel hose clamp.
  • The electrical connections to the throttle body are removed.
  • If the throttle body is not a drive-by-wire system, the accelerator cable and cruise control cable are disconnected and set aside.
  • The bolts retaining the throttle body to the plenum, the gasket, and the throttle body are removed. If the throttle body is being cleaned and tested for re-use, approved chemicals are used in the cleaning process.
  • The new or serviced throttle body is re-attached to the plenum and the bolts torqued to factory specifications.
  • All cables and electrical connections are restored. The intake air snorkel is reconnected.
  • If applicable, the electronic throttle installation and idle re-learn procedures are performed using an appropriate scan tool.
  • Finally, the engine is started, brought to normal operating temperature, and idle speed is checked. The car is road tested to ensure normal operation and no illumination of warning or service lights.

Is it safe to drive with a throttle body problem?

Yes. But, the vehicle may be limited in power or put into what is referred to as limp mode, in order to get the vehicle to a repair facility. If the check engine light is on, or the electronic throttle control warning light is on, but there is no noticeable difference in engine performance, the car can be safely driven. However, it is best to have it diagnosed and repaired at your earliest convenience to avoid unexpected breakdown or possible damage to the catalytic converter.

When replacing the throttle body keep in mind:

  • Many modern throttle bodies have spring loaded sensors and plastic gears that are not intended to be manipulated directly during any diagnostics or inspections. These components are controlled electronically or generate signals. It is best to let a mechanic use approved tests to diagnose the problem.
  • Wiring faults, bad grounds, or bad terminal connections can make it appear as though an electronically controlled throttle has failed. A mechanic will always rule out all other causes before replacing the throttle body.
  • When cleaning the throttle body, special care should be taken to use only special spray cleaners designed to not damage electrical components or sensors.

Mercedes-Benz CL500 V8-5.0L - Radiator - Houston, Texas
If you read nothing beyond this first sentence, just know that Robert is magnificent! On my repair day, Robert showed up promptly at the requested appointment time, sending several heads-up texts prior to his visit. Upon arrival, he very kindly and pleasantly introduced himself, then immediately proceeded to review the requested service and closely inspected the vehicle before bringing out his heavy duty tools. Radiator replacement can be tricky, but Robert tackled it with ease and with a highly professional methodology which can only come from longtime mechanical knowledge and experience. Not only was Robert careful to keep the job site clean and orderly, but he also took delicate care in disassembling components in and around the engine. Once the radiator was successfully replaced and the coolant levels and functionality restored to factory specs, Robert went above and beyond by scanning the vehicle computer for any fault codes, etc. He diagnosed a misfire and tested some ignition components, after which he very kindly suggested what needed to be repaired in the near future. Overall, I will gladly admit that I am very satisfied with the repair work received by Robert. I cannot thank him and YourMechanic enough, as the service received was excellent, affordable, precise, professional and highly convenient. I would highly recommend Robert as a mechanic, as his knowledge, insights, technique and professionalism are without equal.

Mercedes-Benz CL500 V8-5.0L - Pre-purchase Car Inspection - Lumberton, New Jersey
G inspected a Benz CL500 for me. He found multiple issues with the vehicle and saved me a 2 hour drive to Philadelphia to inspect the car myself. His inspection was very thorough; I was highly impressed. He took the time to make sure that I don't get stuck with a lemon; with his findings, he saved me from a potential costly nightmare.
